------------------------------------------

{quote}Quite shocked that commit "9d4d30243b0fc" get merged without basic MRv2 
test and even no YARN JIRA for it!{quote}
[~tangzhankun], commit "9d4d30243b0fc" when in to fix a security problem.  
That's why there's no JIRA and why it's shrouded in mystery.

Who cares? It's all Apache Hadoop. Users have an expectation that this stuff 
will work out of the box and be consistent. They aren't going to say "Oh, of 
course this is completely broken! That part over there is YARN and that part 
over there is MAPREDUCE!"

[~aw], my original patch for "9d4d30243b0fc" did add {{HADOOP_MAPRED_HOME}} to 
Yarn and things did work out of the box.  There was pushback to remove it 
because of the desire to keep Yarn and MR separate.  Given the difficulty 
people seem to be having and that there doesn't seem to be a single fix that 
works for everyone for some reason, perhaps we should revisit that decision?
